Differential Device Modeling Advanced Measurements
白皮书
This paper answers the question “Do I need a true differential signal to measure my non-linear amplifier.” In measuring the non-linear characteristics of many active differential circuits, it is sufficient to measure the single-ended, non-linear response and compute the differential response. This paper explores why even non-linear differential circuits can be correctly measured using single-ended techniques, discusses topology considerations in testing differential circuits, and provides experimental and simulated results to reinforce the concepts.
